Given the volume of marshmallow = [tex]2.25 in^{3}[/tex]
Density of marshmallow = [tex]0.242\frac{g}{cm^{3} }[/tex]
Converting volume from [tex]in^{3} to cm^{3}[/tex]:
[tex]2.25 in^{3} * \frac{16.39 cm^{3} }{1 in^{3} } =36.8775 cm^{3}[/tex]
Calculating the mass from volume and density:
[tex]36.8775 cm^{3} * \frac{0.242 g}{cm^{3} } = 8.92 g[/tex]
Therefore, the mass of marshmallow is 8.92 g
